unofficial-skia is a vcpkg-specific package. With this change ladybird
can be built against skia as provided by system package managers such as
guix, mingw, and (soon) nix. All those packages include a .pc file, so
we use pkg-config.
The Replacement Character (U+FFFD) is most commonly used to signal a
text encoding error, i.e. when a stream of bytes couldn't be converted
to a sequence of code points. For glyphs that don't exist in a
particular font, our rendering logic already does the right thing by
drawing empty boxes (`.notdef`); let's not forcibly turn these into
U+FFFD during rendering.
Skia now uses GPU-accelerated painting on Linux if Vulkan is available.
Most of the performance gain is currently negated by reading the GPU
backend back into RAM to pass it to the Browser process. In the future,
this could be improved by sharing GPU-allocated memory across the
Browser and WebContent processes.
This will reduce log noise when visiting sites
that have a lot of filtered content.
Previously, red error text would be displayed in
the logs for each filtered URL.
Fetch requests from web workers fail CORS checks because the origin is
not inherited from the outside settings. Ensure web worker origin is
correctly inherited from outside settings
GPU painter that uses AccelGfx is slower and way less complete compared
to both default Gfx::Painter and Skia painter. It does not make much
sense to keep it, considering Skia painter already uses Metal backend on
macOS by default and there is an option to enable GPU-accelerated
backend on linux.
This allows selection to work within shadow roots and prevents the
selection being cleared if the mouse moves outside of the current
document or shadow root.
This call is used to inform the chrome that it should display a tooltip
now and avoid any hovering timers. This is used by <video> tags to
display the volume percentage when it is changed.
Now instead of sending the position in which the user entered the
tooltip area, send just the text, and let the chrome figure out how to
display it.
In the case of Qt, wait for 600 milliseconds of no mouse movement, then
display it under the mouse cursor.
Previously, unnecessary boundary checks were being done when
constructing the range objects used to represent find in page matches.
These checks are no longer performed leading to a significant speedup
when performing find in page queries on pages containing a lot of text.
The first step of the find in page algorithm is to walk the layout tree
of each document on the page and construct a list of strings against
which to search for matches.
Previously, this was being done for each new query, even when the
page content hadn't been updated. The output of this process is now
cached in the viewport node of the associated document. This ensures
that this process is no longer repeated unnceessarily.
Unit tests on macOS deadlock because the WebContent process is waiting
for the next opportunity to render before a screenshot is taken. For
some reason unknown to myself, this opportunity never arrives. In
order to not deadlock, screenshot requests are now also processed
separately from rendering.
Since "Character" tokens do not have an "end position", viewing source
drops the source contents following the final non-"Character" token.
By handling the EOF token and breaking out of the loop, we avoid this
issue.
This is an attempt to fix the hanging CI on macOS caused by some
screenshot requests being stuck unprocessed. With this change, we at
least make sure that the HTML event loop processing, which triggers
repainting, will happen as long as there are navigables that need to be
repainted.
This avoids an unecessary lossy conversion for the current time from
double to i32. And avoids an UBSAN failure on macOS that's dependent
on the current uptime.
From SkPaint.h:
"Sets the thickness of the pen used by the paint to outline the shape.
A stroke-width of zero is treated as "hairline" width. Hairlines are
always exactly one pixel wide in device space (their thickness does not
change as the canvas is scaled)."
While we expect stroke-width=0 to simply not be painted.
